X to the second power or x squared.
1
A negative power just means to invert it. Let's say we had x^(-2) - it is the same thing as 1/(x^2).
To get the power of a number you multiply it by itself the specified number of times. For instance, the power 2 to the power of 3 would be 2 X 2 X 2 w 2 which would be 8. The power of 2 to power of 10 would therefore be 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 which would equal 1024. 10 to the power of 10 would be 10,000,000,000. 1 to the power of 10 would be 1.
= Z X and Y are examples. 2 to the power of X multiplied by 2 to the power 2 equals 16 What is X? X=2 2 to the power of 2 (2x2) multiplied (X) by 2 to the power of 2 (2x2) (2x2)4 X (2x2)4 = 4X4 = 16
2 to the 4th power is solved by 2 x 2 x 2 x 2 = 16 2 to the 5th power is solved by 2 x 2 x 2 x 2 x 2 = 32
The equation of a circle through the center (using "^" for power) is: x^2 + y^2 = r^2 To have the center anywhere else, say, through point (a, b), just replace "x" with "x-a" (in this case: x - 1), and "y" with "y-b" (in this case: y - -1, or y + 1).
X to the power 2 is written as - X^2
When a number is raised to a power, it is itself multiplied together the power times, eg:22 = 2 x 223 = 2 x 2 x 2so:210 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2= 2 x (2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2)= 2 x 29= twice 29
(x + 4)(x^2 + 3x + 2) = x^3 + 7x^2 + 14x + 8
(x+y)power 2 -2xy
The power just means how many times you multiply 2 by itself. You would work it out by doing 2 x 2 x 2 x 2 x 2 x 2 = 64
It is always negative when raised to an odd power and always positive when raised to an even power -2 to the third power = -2 x -2 x -2 = -8 -2 to the fourth power = -2 x -2 x -2 x -2 = +16
